PLASI'ER SCRATCHER Fild March 11, 1929 BY w w bid ATTORNEY Patented July 15, 1930 UNITED STATES Application filed March 11,

My invention relates to plaster scratchers. The object of my invention is to provide a novel plaster scratcher, adapted for use for scratching plaster walls and ceilings, '5 which is simple, cheap, strong, durable, not

liable to damage by rough usage, which is light and easy to use, and which iseflicient in its operation. I

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which, illustrates the preferred embodiment of my invention, .1 7'

Fig. 1 is a rear elevationof my improved scratcher, partly broken away. 7

Fig. 2 is an end elevation of the same. Fig. 3 is a plan view of thetooth plate. Fig. 4C is a section on the line 44: of Fig.1. Similar reference characters designate similar parts in the different views.

1 designates a relatively long transverse body portion having in its forwardedge a right angled longitudinal groove 2 in which is mounted a relatively thin plate 3, preferably of springsteel, provided. with parallel forwardly} extending flexible resilient pointed teeth 4. V Y 7 The plate 3 is held releasably fastened to the portion 1, in the groove 2, by aclamping member comprising a plate 5 having one or more transverse holes through which extend securing devices comprisin ,as shown, bolts 6, which also extend through oles 7 in'the plate 3, and through the portion 1, the boltsjhaving on them nuts 8 which bear against the portion 1.

A central. handle 9 extends rearwardly from the body portion 1 at an acute'angle, preferably, to the plane of the teeth 4:. By having the handle disposed centrally and at an angle acute to the plane of the teeth, the scratcher is easily held in a position'in which the teeth will depress grooves in the plaster without tearing it up. I 43 By having the teeth 4 flexible and resilient,

if a tooth strikes a hard object, such as a small lump or stone, the tooth will bend and raise from the plaster surface, without disturbing the even travel of the other teeth, and without deflecting the implement as a whole.
